I doubt they'll ever do this, Zombies is just like an arcade type of game (not that the whole series isn't an arcade shooter series). IMO they should add like a real story, a way to win (but REALLY REALLY DAMN HARD), and other cool stuff.
I wouldn't personally buy it, but I know that it would be a major success. I've heard tons of people say the same exact thing.
The game is nice but it gets boring after a while.
I like the newer Nazi zombies the best. Black ops you know.
I have also thought about the idea of having a separate game which completely revolves around the Zombies game-mode. Maybe there would be a mode featured in the game which allowed you to work in teams of 30 and explore an entire town. This would possibly include more survival tactics, as featured in The Walking Dead and DayZ.
I don't play COD games, cuz they're too noobish(IMO), however that def. isn't true.I like zombies on Black Ops, accustomed play it all the time with my friends.
